IMO about as healthy as an anemic 3rd degree burn victim with long covid :)
Right now, you can leave your Google job and raise a seed/pre-seed of $1-5M at a $30-50M valuation to build on Ethereum.
You'd have to be nuts to -- on purely financial motives -- decide to work on Bitcoin instead.
That's OK because we don't want the merc's, we want passionate dedicated individuals, but consider if you're trying to build a bitcoin company and that is the ability to pay for talent you have to compete with. It is going to suck.
